Temtop Laser PM2.5 Sensor (Upgraded to 4th-gen.)The particles pass through the professional light source from QSI, combined with the MIE scattering principle and the smart particle inversion algorithm to determine multi-channel concentration of PM2.5, PM10, and TSP. |
Dart Electrochemical HCHO SensorThe HCHO gas pass through the electrolyte, combined with the principle of chemical electrode reaction, and a built-in algorithm to convert various electrical signal into the formaldehyde concentration values. |
SenseAir NDIR CO2 SensorUsing NDIR (non-dispersive infrared) gas sensing technology, based on the Lambert-Beer absorption law, combined with the built-in CO2 gas fingerprint feature analysis algorithm to determine the concentration of CO2. |
